hi,
what is the SDHC memory diffrent between class 2 and class 10?

I heard class 2 used in k-x might loss it performance. is it correct??

Use the "search" function and you will find several threads explain the differences between the class numbers of SD cards.

To answer your original question...YES, a class 10 would be just fine for your K-x, as well as a class 6 card. Any brand is fine, dont let the marketing hype of feeling the need to buy the most expensive one fool you..they are all made in the same factories and have a success/fail rate all the same.

Might be a dumb question here. How do you tell what class a SD card is?
I have a number of them and no markings indicating the class. I suspect they are on the low end as I have noticed on my K-x when shooting a three shot bracketed group for an HDR that at times it seems slow to take the shots.

Jasvox, Thanks for the advised

LScrabeck, do u see the SD card has a circle join with a number? that's one is a class

[LScrabeck]

Jasvox,
Thanks--Got a 4 in my K-x. In your opinion, is that fast enough?

[jolepp]

The class figure simply means the highest sustained write speed the card can do in MBytes/s. As such it provides for meaningful comparison between brands. The write speed is an issue with video, not so much with still pictures. What works with video should work otherwise, so recording, say, two minutes and playing it back should tell you whether your card is fast enough; no problems means it is. [edit: In general class 6 should be fast enough, class 4 might work though.]

I use Class 10 from Transcend , work fine in my K-X and K-5

SanDisk class 10 here. Works like a charm.

Video is where the class speed really matters. With a class 2 card, you'll most likely only be able to record around 30 seconds to 2 minutes before the buffer fills up. A good class 4 card should be able to record the full 24 minutes. IMO a Class 10 card is overkill for this camera.

When I shoot video, I always use a class 10 or 6. Originally got the class 10 because someone said it might reduce the delay when the buffer is full. I've not noticed a difference in performance between the class 10 or 6. I suspect the class 6 has more bandwidth than the K-x can actually write.

Transfer speed from card to PC matters a lot to me, and was a big reason why I went for a class 10 card.

Quick test results:
310MB Mov file from card to PC: 19.2MB/s average speed.
310MB Mov file from PC to card: 18.1MB/s average speed (can't imagine copying to the card but did the test anyways).

21 DNG files (214MB in total) from card to PC: 19.45MB/s average speed.

I'm on a 32GB card and do expect it to fill up from time to time - if it had ben 8GB then I might not have been as eager to go for class 10, since the amoung of data would be much less.

The card is specified as being capable of 30MB/s. Whether it's my card reader not being fast enough or the specifications being optimistic (as they often tend to be) or something third is unknown to me. But I do appreciate the speed I'm getting.

I have Transcend 16GB Class 10, working great with my K-x, might be overkilled with photos, but it's good for video shooting.

I use a Kingston 8GB Class 4 card, an inexpensive but quality card. No problems with stills or video.

Nonetheless, when I tested the card using hard disk benchmark software, the card did reach Class 10 speeds: 10.1 MB/s write, 17.2 MB/s read.

I use a 8GB Transcend Class 10, works like a charm for images and video.

I heard some people had problems with the Class 10 Transcend in their K-x's. But I guess not for Lester! 4GB Transcend Class 6 worked without fail for me. Never experienced any data loss, etc.
